FIELD

Embodiments of the present disclosure generally relate to cables for providing electrical power and telemetry to downhole tools.

BACKGROUND

Certain opto-electrical cables for providing both electrical power and telemetry to downhole tools include a tube formed of semicircular-profile wires that surround optical fibers. Traditionally, such opto-electrical cables, when subjected to longitudinal strain and/or compressive forces, are subject to “milking,” where filler gel and/or optical fibers within the tube are squeezed out of the tube. Manufacturing imperfections may increase the occurrence of milking.

SUMMARY

The present disclosure provides for an opto-electrical cable. The opto-electrical cable includes an opto-electrical cable core, and a polymer layer longitudinally and circumferentially surrounding the opto-electrical cable core. The opto-electrical cable core includes a wire, at least one channel formed within the wire and extending longitudinally along the wire, and optical fibers extending longitudinally within each channel.

The present disclosure provides for a multi-component cable. The multi-component cable includes electrical conductor cables and opto-electrical cables. Deformable polymer longitudinally and circumferentially surrounds the opto-electrical cables and the electrical conductor cables. The opto-electrical cables and the electrical conductor cables are arranged within the deformable polymer in a coax configuration, a triad configuration, a quad configuration, or a hepta configuration. Each opto-electrical cable includes an opto-electrical cable core. Each opto-electrical cable core includes a wire, at least one channel formed within the wire and extending longitudinally along the wire, and optical fibers extending longitudinally within each channel. A polymer layer longitudinally and circumferentially surrounds each opto-electrical cable core.

The present disclosure provides for a method. The method includes providing a wire having at least one channel extending longitudinally within and along the wire. The method includes providing optical fibers extending longitudinally within each channel. The wire and the optical fibers form an opto-electrical cable core.
